I IMPROVEMENT IN CARRIAGE-WHEEL HUBS.

ihe Schedule referred to in these Letters Patent and making part oitil'e name.

To all whom it may concern:

Be it kowu that I,W1LLnuu J. Anmncrox, of Jefferson county, Georgia, have invented a new and valuable Improvement in the Wheel-Hub; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings and to the letters of reference marked thereon.

Figure 1 is a transversesection.

Figure 2is a longitudinal section of the hub and box, with a portion oft-he latter shown entire.

Figure 3 is a plan of the hub.

Like letters of reference indicate correspomling parts.

Letters to a, fig. 2, represent' mcrtisesfinto which the spokes enter.

' Letters 1) I) represent tenons which dovetail with the shallow mortiscs of the smaller transverse section.

Letters 0 c, fig. 3, represent short tenons of smaller transverse sections which fit to corresponding parts of larger transverse sections when all the parts are united and the hub complete.

The hub proper may be made of any desired shape or size, and of wood or-metal. It is composed of two separate disks,-the larger, A, having on its transverse 'face the tenou's and mortises into and between which the spokes enter; the smaller, B, presenting by its opposing and transverse face shorter and shallower corresponding tenons and mortises, into and between which the tenons and mortises of the larger section are received.

These two sections are held together, first by a num ber of small bolts passing longitudinallythrough every third or alternate space intervening between the spokes, and secondly by a detatchable box, through which passes the axle. countersunk at one end, and has ascrew and not on the other end, thus becoming by its screw and nut the means by which the two sections of the hub may be taken apart, and allow of the removal or insertion of the spokes without the necessity of unrimming the wheel, at the same time becoming the means, by tightening the screw, of closely and firmly holding the two sections and spokes together.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent of the United States, is-

' 1. The combination of the disk A, provided with the tenons b, with the disk B, provided with the tenons 0, when the tenous c are included between the tenons b in the completed hub, in the manner and for the purpose described. v

2. The detachable shouldered box 0 combined with the disks A B, substantially as described.
